hi @user438 and welcome to Cursor Forum.
Thank you for your post.
Cursor is tracking actual consumption of tokens and model instead of counting requests.
There is no hard limit on actual requests but rather based on how much you use up.
You can see your usage in Dashboard > Usage, there is a Included Usage Summary which shows how much you used as included in your plan.
Once you reach your plan usage limit you can either switch to Auto model which is not charged, Usage Based Pricing if you prefer to continue working with premium models or upgrade to a higher plan if that suits your usage better.
You can see more how the token usage works and how to optimize your usage.
